Easy Chocolate-Raspberry Mousse, made with 1 avocado or the equivalent in pre-made avocado mash, 2 ripe bananas, 1 cup frozen raspberries, 1/2 cup almond butter, 2 tablespoons clarified butter, 1/4 cup Dutch processed cocoa powder, 1 teaspoon vanilla paste, 1/2-1 teaspoon real almond flavoring, and a pinch of salt, all pureed together until smooth and chilled thoroughly.

I’ve soliloquized on leftovers here many a time, because few of us don’t have, and use, them with a certain amount of frequency. It can be, as I’ve mentioned, something that lives on only as the humorously known YMCA (Yesterday’s Muck Cooked Again), or with a little thought and effort, it can be a whole new being. It can be a watery mishmash of tasteless goo, a slumgullion, or with some inventiveness and luck, a tasty new experience in and of itself. My recent post on rethinking the remains of broth-making is one example of happily finding the latter.

In addition to making use of the extant collection of remains on display in the museum of the refrigerator and cupboards, one can always prepare those foundational foods that become ingredients for a gallimaufry of further dishes and meals. It’s a sort of slower or longer-term version of mise en place. One that has proven particularly useful to me is the simple fix of mashing a few ripe avocados with lemon or lime juice and a pinch of salt and keeping them in the fridge in a zipper bag. In a two-person family that lives in a warm climate, it’s hard to keep whole avocados fresh for any length of time, so since this particular family is also a one-car family and I don’t wish to finagle grocery shopping almost daily, this simple avocado mash stores, unchanged, in the icebox for a fair length of time while I take out daily bits, squeeze the air out of the bag and seal it, and chill it again until the next use.That easy fix for my avocado problem (you can decide whether that means spoilage or addiction in this case) has presented a whole world of possibilities not previously quite so accessible. Straight out of the bag, the mash can go directly into any number of dishes, both savory and sweet: add a little cumin and chipotle and cilantro, and it’s guacamole; mash in a ripe banana and some cocoa powder and vanilla and honey, and it’s chocolate pudding. Or the avocado can just go directly into my mouth, because lemony avocado mash is a delicious accompaniment to all sorts of good meals.

The broth-offspring remix turns out to be pretty versatile, too. The second time around, instead of making separate dishes of carrot pudding and beef pate, I combined the two ingredients into a different sort of pate that gave me nearly two weeks of very flavorful protein that I could eat in a wide variety of ways. The first time, I ate it simply as a room temperature mousse, sprinkled with a little cinnamon, and it was very satisfying not only because I liked the taste and the creamy texture but because I knew it was a reasonably good source of protein and a great way not to waste–you guessed it–leftovers. Unfamiliar to my palate and yet instant comfort food. Easy to fix even the first time around, too; the broth itself, while it takes a little forethought to stock up the slow cooker with the mix of veg and bones and spices that I like, just tends itself for the long cooking, other than the occasional stir to keep all of the ingredients dunked in the liquid. Straining the finished broth and picking out the parts takes some time, yes, but the process of recombining those parts into the new mousse iteration is really pretty easy and fast work, and getting a couple of weeks’ eating (or one big party’s hors-d’oeuvre spread) out of it is a rather fine payoff.Beef Ginger Mousse

This, given the leftover-centric nature of the concoction, was a truly approximate recipe. I used about 1 cup each of leftover beef bits/marrow and carrots from beef broth making, 3 tablespoons of clarified butter, 1/2-3/4 teaspoon of ground cinnamon, 3-4 eggs, a sprinkle of salt, 2 tablespoons of ginger juice and 1/2 cup of the beef broth. I pureed it all thoroughly until it was the consistency of a creamy pudding, spooned it into buttered small casserole, set that casserole on top of a clean dish cloth in a larger casserole, set the rig on the middle rack of the oven, filled the larger pan with an inch of water, and baked it like a standard custard. Given my oven’s unconventional concept of temperature, I recommend to anyone attempting replication of this ‘recipe’ that you use your own time-and-temp standards for custard making and just watch the progress until the mousse responds properly when the pan’s given a slight jiggle. Lightly set, neither wet nor dry. Serve room temperature, or chill for future use.

And soon, my friends, I will show you how you can use this mousse further in such repasts (the only term truly appropriate for feasts of leftovers, don’t you think?) as Ploughman’s Lunch and Cavegirl Quiche. I’m nice that way.
